FIELD: high-frequency communications over power transmission line conductors. SUBSTANCE: high-frequency wave- trap that can be used in power engineering to transfer supervision control, alarm, and relay protection signals to power-generating equipment has power reactor, protective gear, adjusting unit incorporating first capacitor, second capacitor, inductance coil, resistor, and second inductance coil inserted between common lead of second capacitor and first inductance coil and common lead of first capacitor and resistor. To this end high-frequency wave-trap (its alternative design) has power reactor, protective gear, and also adjusting unit incorporating capacitor, first inductance coil, resistor, and second inductance coil inserted between common lead of capacitor and first inductance coil and common lead of resistor and protective gear. EFFECT: enlarged rejection band at high electric strength of wave-trap. 4 cl, 3 dwg |
